Gear Design Software

Powerful for Experts, Simple for Beginners

Gear Design Software
Gears are modeled as full mathematical involutes. Design spur gears, escapements, ratchets, elliptical gears, heck design gears with arbitrary shapes that were imaginary, until you create them.

Seriously cool features like point and click spoke design with hundreds of spoke patterns.
